General Question

How can I contact/find angel investors in Silicon Valley with an interest in telecom?

My husband has patented a new waveform, a spiral-based signal modulation that addresses the spectrum crisis. We are at very early stage and are in Phase 0 R&D with a satellite modem maker—and in contract discussions with mobile backhaul modem makers. We are raising a last seed round. This is a disruptive telecom technology that addresses better utilization of spectrum with order of magnitude improvement. I want to find some angels in Silicon Valley to approach. <the underlying play is my husband took the foundational math of telecom, Euler’s formula, and extended it to fractional powers to made it non-periodic and non-linear>
